Application October 5,

2 Claims.

My invention has reference to curbing armor for pavements constructed ofconcrete and the like to protect the concrete against being chipped andbroken away by the wheels of vehicles.

It is a purpose of my invention to provide a curbing armor formed ofbendable metal and so constructed as to permit of its being readily bentto accurately conform to the curvature of a curbing at a corner.

It is a further purpose of my invention to provide a curbing armorwhich, while capable of being bent in conformity with any curbingcurvature, in its association with a concrete pavement is anchored orbonded to the concrete with such security as to withstand the roughusage to which a corner curbing is subjected by vehicles, withoutrupturing the bond between the armor and concrete.

Another purpose of my invention is the provision of an armor which isstructurally and functionally characterized by displacing portions ofthe metal of which the armor is formed to permit bending of the armor toany prescribed curvature of curbing, and utilizing those displaced metalportions to form elements for anchoring the armor to the concrete.

Still another purpose of my invention is the provision of an armor whichforms the side face of a curbing and the top surface thereof, thatportion of the armor constituting the top surface having upstruckprotuberances which present a .surface upon which pedestrians in walkingcannot slip, and which protuberances are so formed as to provideshouldered pockets in which concrete is received to form an additionalbond. between the concrete curbing and the armor.

I will describe only one form of curbing armor embodying my invention,and will then point out the novel features thereof in claims.

In the accompanying drawing:

Fig. 1 is a perspective view of a section of concrete pavement havingapplied to the curbing thereof one form of armor embodying my invention.

Fig. 2 is an enlarged plan view showing a section of the armor embodyingmy invention.

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2, but with thearmor applied to a concrete curbing as in Fig. 1.

Fig. 4 is a view showing a section of the armor in perspective.

In carrying out my invention, I provide a body or member formed of anymaterial suitable for the purpose, such as steel. The body is in theform of an angle bar as it consists of two parts,

legs, or plates 15 and 16 arranged substantially at right angles to eachother. In manufacture, the angle bars are made in suitable lengths, andthe precise angle of the plates is in keeping with the angular relationof the side face-and top surface of the particular curbing to which thearmor is applied.

As shown in Figs. 2 and 4, the plate 16 which forms the top surface ofthe curbing is cut transversely along two converging lines and atintervals along its length to permit displacement of those portions ofthe metal between adjacent cuts for the dual purpose of forming wedgeshaped gaps 17 in the plate to permit bending of the bar as a whole, andlegs 18 which are subsequently bent to provide anchor members. Thus itwill be manifest that in the manufacture of the armor, all metal ofwhich the bar is formed is conserved and utilized for some usefulpurpose in the adaptation of the armor 7 to a curbing.

In forming the plate 16 with the gaps 17, the bar as a whole can be bentto the radius required for its conformation to a curbing of anycurvature, it being understood that the plate 15 can be bent readilyonce the legs are displaced to form the gaps. The frequency of the gapsis of course determined by the degree of curvature of the curbing.

The legs 18 are converted into anchor members by bending each of themdownward or inward between the plates 15 and 16 so as to form anattenuated loop which is closed by bringing the free end of the leg intocontact with the inner side of the plate 15, as best shown in Fig. 3. Itwill be understood, however, that the legs can be bent to any formdesired so long as they function as anchor members when applied to abody of concrete for bonding the armor to the concrete.

As an additional anchoring means for the armor, rods 19 are provided,one for each of the anchor members 18. Each rod 19 is bent at one end toform an angular extension 20, while the other end is bent to form an eye21 by which the rod is attached to the corresponding anchor member 18.To apply the rod, the eye 21 is left open a distance slightly greaterthan the metal thickness of the anchor member so that by positioning theeye to receive the anchor member edgewise in the gap, the eye of the rodcan be extended through the loop of the anchor member. Now by moving therod to the angular position which it finally assumes as applied to acurbing, the rod is locked to the anchor member.

For the dual purpose of presenting to the upper side of the plate 16 asurface upon which pedestrians cannot slip in walking, and providing abond between the plate and the concrete therebeneath, the plate 16 isformed with staggered protuberances 22. These are formed by cutting themetal lengthwise along parallel lines and for relatively short distancesand then punching the portions between companion cuts. The outstrikingof these portions is such that they assume a convex form on the outersides and concave form on the inner sides. In consequence of theconstruction, pockets having angular shoulders are formed in theunderside of the plate in which concrete is received to bond the plateto the concrete curbing.

With the armor applied to a concrete curbing, as illustrated in Figs. 1and 3, the plate 15 forms a protecting covering for the side face of thecurbing, while the plate 16 constitutes a covering for the upper surfaceof the curbing. The plate 16 lies flush with the surface of thepavement, as shown in Fig. 3, and the protuberances 22 present a surfaceupon which pedestrians cannot slip.

In the adaptation of the armor to the corner or curb part of thecurbing, the bar is bent on a radius corresponding to that of thecurbing, so that as applied the bar forms a continuous and contiguousprotecting armor f or the curbing.

The armor as a whole is securely bonded to the curbing concrete by theanchor members 18 which are embedded in and completely surrounded by theconcrete in the manner illustrated in Fig. 3. The anchor rods 19 arelikewise embedded in the concrete and positioned diagonally of thecurbing,

, and being attached to the anchor members 18 supplement the bondingaction of the member to maintain the armor in fixed position uponthecurbing.

Although I have herein shown and described only one form of curbingarmor embodying my invention, it is to be understood that variouschanges and modifications may be made herein without departing from thespirit of my invention and the spirit and scope of the appended claims.

I claim:

1. An armor for curbings comprising; a member angular in cross sectionhaving one part to form the face of a curbing and another part to formthe top surface of the curbing, the second mentioned part havingtransverse gaps therein to allow bending of the member to conform to thelongitudinal curvature of the curbing; anchor elements secured to themember between said parts; and anchor rods one for each of the anchorelements, each of the rods having a looped end formed with a gap whichpermits the loop to be extended around the element only when in oneposition so that by moving it to another position after application, therod is secured to the element against displacement.

2. An armor for curbings, comprising; a member angular in cross sectionhaving one part to form the face of a curbing and another part to formthe top surface of the curbing, the top surface-forming part havingtransverse slits therein in pairs at intervals along the length of thepart, the portions of said part between the slits of each pair extendingbetween the two parts to form substantially closed loop anchor elements;and anchor rods one for each of the anchor elements, each of the anchorrods having a looped end extending around the corresponding anchorelement.
